Abstract
Example embodiments are directed to light sensing circuits having a relatively simpler structure by using light-sensitive oxide semiconductor transistors as light sensing devices, and remote optical touch panels and image acquisition apparatuses, each including the light sensing circuits. The light sensing circuit includes a light-sensitive oxide semiconductor transistor in each pixel, wherein the light-sensitive oxide semiconductor transistor is configured as a light sensing device, and a driving circuit that outputs data. The light sensing circuit may have a relatively simple circuit structure including a plurality of transistors in one pixel. As a result, the structure and operation of the light sensing circuit may be simplified.
